I am for the "immediate, unconditional, and universal" enfranchisement of the black man, in every State in the Union. [Loud applause.] Without this, his liberty is a mockery; without this, you might as well almost retain the old name of slavery for his condition; for in fact, if he is not the slave of the individual master, he is the slave of society, and holds his liberty as a privilege, not as a right. He is at the mercy of the mob, and has no means of protecting himself.
How does the repetition of the phrase “without this” support the paragraph’s argument?
